RANDOM EXPERIMENT: An experiment in which all possible outcome are known and the exact output cannot be predicted in advance is called an random experimentWhen we throw a coin. Then either a Head (H)or a Tail(T)appears.A dice is a solid cube, having 6 faces, marked 1,2,3,4,5,6 respectively when we throw a die, the outcome is the number that appear on its top face.A pack of cards has 52cards. It has 13 cards of each suit, namely Spades, Clubs, Hearts and diamonds.Cards of spades and clubs are black cards.Cards of hearts and diamonds are red cards.There are 4 honours of each suit.These are aces, king, queen and jack.These are called face cards.Sample space: When we perform an experiment, then the set S of all possible outcomes is called the Sample Space. For example, in tossing a coin, S = {H, T} and if two coin are tossed, then S = {HH, HT, TH, TT}.
